WebJun 1, 2024 · Two novel azeotropic ternary mixtures of RE170/R1234yf/R152a were developed in order to improve cooling capacity and performance of a dimethyl ether refrigeration cycle. The mass ratios were purposefully selected to offer high cycle efficiency COP, high specific cooling capacity q e, small specific volume of vapour, reduced … WebAn ether is two hydrocarbon chains connected to ONE oxygen atom. An ethyl group is 2 carbon atoms long. The problem says (or should say) “diethyl” the prefix “di” indicates 2. So the molecule is 2 chains of carbon atoms. The chain is an ethyl chain, and that is 2 carbon atoms long. So: here are 2 ethyl chains: (1) CH3-CH2- ***and*** (2) -CH2-CH3
